Freee proposes a new conception of participation for art. We address current debates on art and participation, for example in the theories and positions of Grant Kester and Claire Bishop. These two positions set a polarized debate between a social and collaborative ethic in art, and the shock tactics of an avant-garde art. For us, publics are not reducible to the individuals found in the marketplace or the political and cultural encounters of the spectacle (consumers, fans, viewers, customers, etc.). A public has agency, which is why we prefer performative actants (witnesses, signatories, advocates, etc.).
